MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"The table of locally available contexts.
This table provides information to SNMP Command
Generator applications so that they can properly
configure the vacmAccessTable to control access to
all contexts at the SNMP entity.
This table may change dynamically if the SNMP entity
allows that contexts are added/deleted dynamically
(for instance when its configuration changes). Such
changes would happen only if the management
instrumentation at that SNMP entity recognizes more
(or fewer) contexts.
The presence of entries in this table and of entries
in the vacmAccessTable are independent. That is, a
context identified by an entry in this table is not
necessarily referenced by any entries in the
vacmAccessTable; and the context(s) referenced by an
entry in the vacmAccessTable does not necessarily
currently exist and thus need not be identified by an
entry in this table.
This table must be made accessible via the default
context so that Command Responder applications have
a standard way of retrieving the information.
This table is read-only. It cannot be configured via
SNMP.

"::={ vacmSecurityToGroupEntry 5}-- Information about Access Rights ***********************************
vacmAccessTable OBJECT-TYPESYNTAXSEQUENCEOF VacmAccessEntry
MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"The table of access rights for groups.
Each entry is indexed by a groupName, a contextPrefix,
a securityModel and a securityLevel. To determine
whether access is allowed, one entry from this table
needs to be selected and the proper viewName from that
entry must be used for access control checking.
To select the proper entry, follow these steps:
1) the set of possible matches is formed by the
intersection of the following sets of entries:
the set of entries with identical vacmGroupName
the union of these two sets:
- the set with identical vacmAccessContextPrefix
- the set of entries with vacmAccessContextMatch
value of 'prefix' and matching
vacmAccessContextPrefix
intersected with the union of these two sets:
- the set of entries with identical
vacmSecurityModel
- the set of entries with vacmSecurityModel
value of 'any'
intersected with the set of entries with
vacmAccessSecurityLevel value less than or equal
to the requested securityLevel
2) if this set has only one member, we're done
otherwise, it comes down to deciding how to weight
the preferences between ContextPrefixes,
SecurityModels, and SecurityLevels as follows:
a) if the subset of entries with securityModel
matching the securityModel in the message is
not empty, then discard the rest.
b) if the subset of entries with
vacmAccessContextPrefix matching the contextName
in the message is not empty,
then discard the rest
c) discard all entries with ContextPrefixes shorter
than the longest one remaining in the set
d) select the entry with the highest securityLevel
Please note that for securityLevel noAuthNoPriv, all
groups are really equivalent since the assumption that
the securityName has been authenticated does not hold.

Command Generator applications to coordinate their
use of the Set operation in creating or modifying
views.
When creating a new view or altering an existing
view, it is important to understand the potential
interactions with other uses of the view. The
vacmViewSpinLock should be retrieved. The name of
the view to be created should be determined to be
unique by the SNMP Command Generator application by
consulting the vacmViewTreeFamilyTable. Finally,
the named view may be created (Set), including the
advisory lock.
If another SNMP Command Generator application has
altered the views in the meantime, then the spin
lock's value will have changed, and so this creation
will fail because it will specify the wrong value for
the spin lock.
Since this is an advisory lock, the use of this lock
is not enforced.
"::={ vacmMIBViews 1}vacmViewTreeFamilyTable OBJECT-TYPESYNTAXSEQUENCEOF VacmViewTreeFamilyEntry
MAX-ACCESSnot-accessible
STATUScurrentDESCRIPTION"Locally held information about families of subtrees
within MIB views.
Each MIB view is defined by two sets of view subtrees:
- the included view subtrees, and
- the excluded view subtrees.
Every such view subtree, both the included and the
excluded ones, is defined in this table.
To determine if a particular object instance is in
a particular MIB view, compare the object instance's
OBJECT IDENTIFIER with each of the MIB view's active
entries in this table. If none match, then the
object instance is not in the MIB view. If one or
more match, then the object instance is included in,
or excluded from, the MIB view according to the
value of vacmViewTreeFamilyType in the entry whose
value of vacmViewTreeFamilySubtree has the most
sub-identifiers. If multiple entries match and have
the same number of sub-identifiers (when wildcarding
is specified with the value of vacmViewTreeFamilyMask),
then the lexicographically greatest instance of
vacmViewTreeFamilyType determines the inclusion or
exclusion.
An object instance's OBJECT IDENTIFIER X matches an
active entry in this table when the number of
sub-identifiers in X is at least as many as in the
value of vacmViewTreeFamilySubtree for the entry,
and each sub-identifier in the value of
vacmViewTreeFamilySubtree matches its corresponding
sub-identifier in X. Two sub-identifiers match
either if the corresponding bit of the value of
vacmViewTreeFamilyMask for the entry is zero (the
'wild card' value), or if they are equal.
A 'family' of subtrees is the set of subtrees defined
by a particular combination of values of
vacmViewTreeFamilySubtree and vacmViewTreeFamilyMask.
In the case where no 'wild card' is defined in the
vacmViewTreeFamilyMask, the family of subtrees reduces
to a single subtree.
When creating or changing MIB views, an SNMP Command
Generator application should utilize the
vacmViewSpinLock to try to avoid collisions. See
DESCRIPTION clause of vacmViewSpinLock.
When creating MIB views, it is strongly advised that
first the 'excluded' vacmViewTreeFamilyEntries are
created and then the 'included' entries.
When deleting MIB views, it is strongly advised that
first the 'included' vacmViewTreeFamilyEntries are
deleted and then the 'excluded' entries.
If a create for an entry for instance-level access
control is received and the implementation does not
support instance-level granularity, then an
inconsistentName error must be returned.
"::={ vacmMIBViews 2}vacmViewTreeFamilyEntry OBJECT-TYPESYNTAX VacmViewTreeFamilyEntry
MAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"Information on a particular family of view subtrees
included in or excluded from a particular SNMP
context's MIB view.
Implementations must not restrict the number of
families of view subtrees for a given MIB view,
except as dictated by resource constraints on the
overall number of entries in the
vacmViewTreeFamilyTable.
If no conceptual rows exist in this table for a given
MIB view (viewName), that view may be thought of as
consisting of the empty set of view subtrees.

"::={ vacmViewTreeFamilyEntry 1}vacmViewTreeFamilySubtree OBJECT-TYPESYNTAXOBJECTIDENTIFIERMAX-ACCESSnot-accessibleSTATUScurrentDESCRIPTION"The MIB subtree which when combined with the

defines a family of view subtrees.
"::={ vacmViewTreeFamilyEntry 2}vacmViewTreeFamilyMask OBJECT-TYPESYNTAXOCTETSTRING(SIZE(0..16))
MAX-ACCESSread-createSTATUScurrentDESCRIPTION"The bit mask which, in combination with the
corresponding instance of vacmViewTreeFamilySubtree,
defines a family of view subtrees.
Each bit of this bit mask corresponds to a
sub-identifier of vacmViewTreeFamilySubtree, with the
most significant bit of the i-th octet of this octet
string value (extended if necessary, see below)
corresponding to the (8*i - 7)-th sub-identifier, and
the least significant bit of the i-th octet of this
octet string corresponding to the (8*i)-th
sub-identifier, where i is in the range 1 through 16.
Each bit of this bit mask specifies whether or not
the corresponding sub-identifiers must match when
determining if an OBJECT IDENTIFIER is in this
family of view subtrees; a '1' indicates that an
exact match must occur; a '0' indicates 'wild card',
i.e., any sub-identifier value matches.
Thus, the OBJECT IDENTIFIER X of an object instance
is contained in a family of view subtrees if, for
each sub-identifier of the value of
vacmViewTreeFamilySubtree, either:
the i-th bit of vacmViewTreeFamilyMask is 0, or
the i-th sub-identifier of X is equal to the i-th
sub-identifier of the value of
vacmViewTreeFamilySubtree.
If the value of this bit mask is M bits long and
there are more than M sub-identifiers in the
corresponding instance of vacmViewTreeFamilySubtree,
then the bit mask is extended with 1's to be the
required length.
Note that when the value of this object is the
zero-length string, this extension rule results in
a mask of all-1's being used (i.e., no 'wild card'),
and the family of view subtrees is the one view
subtree uniquely identified by the corresponding
instance of vacmViewTreeFamilySubtree.
Note that masks of length greater than zero length
do not need to be supported. In this case this
object is made read-only.
